As a specialized steel plate supplier, Parvan Steel Complex provides the opportunity to supply $40$mm hot rolled plates in various dimensions with valid mill test certificates in the shortest possible time.

Introduction to $40$mm ST37 Steel Plate

ST37 hot rolled plate is a low-carbon steel offering high formability and adequate strength, produced according to recognized DIN $17100$ and EN 10025 standards. At a 40mm thickness, this plate enters the “Heavy Plate” category and is utilized in structures demanding high resistance to deformation, extreme stability, and significant thickness.

A $40$mm thickness is typically applied in the following projects:

• Massive road and rail structures
• Chassis of ultra-heavy machinery
• Large industrial equipment
• Base plates for extra-heavy columns
• Walls of large pressure vessels
• Structural frames in power plants and refineries

Technical Specifications of ST37 Steel Plate ($40$mm Thickness)

The $40$mm ST37 plate adheres to standard ST37 technical specifications. However, at this thickness, dimensional stability and buckling resistance become critically important.

Mechanical Properties:

• Yield Stress: Minimum 235 MPa
• Tensile Strength: 360 MPa
• Elongation: Minimum 20%
• Production Process: Hot Rolling

Chemical Composition:

• Carbon ©: 0.17% to 0.20%
• Manganese (Mn): 0.35% to 0.65%
• Silicon (Si): 0.15%$0.35\%$
• Phosphorus (P): Maximum 0.045%
• Sulfur (S): Maximum 0.045%

This chemical composition ensures easy weldability and good deformability while maintaining structural strength.

Weight of 40mm ST37 Steel Plate

Calculating the weight for a $40$mm thickness is crucial, as this product belongs to the extra-heavy plate category, significantly impacting transportation, loading, and structural design.

• Formula: Weight=Thickness (m)×Density
• Weight per square meter of $40$mm ST37 plate: $314$ kg

Weight Table for Hot Rolled Plate in Common Dimensions:

• $1\times 2$ meters: $628$ kg
• $1.5\times 3$ meters: 1413 kg
• $2\times 6$ meters: $3768$ kg
• $2\times 12$ meters $7536$ kg

Industrial Applications of $40$mm ST37 Plate

1. Heavy Bridges and Road Structures

This thickness is considered a standard choice for installation in load-bearing beams, extra-heavy base plates, large connection plates, and structural diaphragms.

2. Heavy Industry and Ultra-Heavy Machinery

The $40$mm plate plays an essential role in manufacturing the chassis of giant excavators, mining and drilling machinery, and industrial devices operating under severe loads.

3. Pressure Vessels and Industrial Boilers

This thickness is an ideal option for fuel storage tanks, power plant tanks, and industrial steam boilers, as the high thickness guarantees resistance against internal pressures.

4. Extra-Heavy Column Bases in Industrial Projects

Base plates in power plants, factories, refineries, and heavy metal industries are predominantly manufactured using $30$mm to $60$mm plates.

5. Military Industries and Robust Components

It is utilized in producing resilient plates, sturdy frames, and metal structures requiring maximum resistance.

Advantages of $40$mm ST37 Steel Plate

• High strength and stability for exceptionally heavy loads.
• Offers a highly competitive hot rolled steel plate price compared to alloy steels.
• Excellent weldability without the need for complex heat treatments.
• Desirable resistance against impact and deformation.
• Can be cut using oxy-fuel, plasma, or waterjet.
